MEASUREMENT OF OPTICAL ABERRATIONS BY MULTISPECTRAL PHASE DIVERSITY
Centre National d'Etudes Spatiales CNES - 10/05/2017
Improvement process of image quality thanks to a spectral phase diversity algorithm The aim of this invention is to improve the images taken by the satellites so they are more precise and less blurred. Images are improved with a flaw estimation either by an on board actuation system or by a ground image processing software.
- Cost reduction and less complexity (no dedicated sensors needed) - Images much sharper Optical flaws caracterisation - Ground optimisation of ground deconvolution - Used in a loop of active optics A cost effective and efficient technology - No need of dedicated sensors - Offers a wide range of measures
Spatial - All systems of optical observations of the earth Photography - Cameras Video - Camera in cars - Video Drone
